Core drilling is one of the most fundamental and reliable techniques in mineral exploration. It serves as a direct method of obtaining subsurface samples that provide a continuous record of the geological formations beneath the surface. The cylindrical samples, known as cores, give geologists valuable insights into the composition, texture, and structure of rocks, helping to identify and evaluate potential mineral deposits. The process typically begins with the use of a diamond-tipped drill bit, which cuts through various layers of rock while preserving the core inside a hollow tube. These cores are then carefully extracted, logged, photographed, and analyzed in laboratories. Through this detailed examination, geologists can determine the type, grade, and distribution of minerals present — essential data for accurate resource estimation and feasibility studies. Unlike other drilling methods, such as reverse circulation (RC) drilling, core drilling provides more detailed geological information because it maintains the integrity of the rock sample. This makes it particularly valuable for structural analysis, stratigraphic interpretation, and geotechnical assessments. In modern exploration, core drilling rigs are equipped with advanced hydraulic and digital control systems that allow for greater depth accuracy, improved safety, and better data acquisition. Furthermore, precise core orientation techniques enable geologists to understand the true position of geological structures, such as faults, folds, and veins, which are critical in mine design and planning. It is also worth emphasizing that core handling and preservation are key aspects of successful exploration. Improper labeling, contamination, or poor storage can lead to data loss and misinterpretation. Therefore, maintaining a standardized core logging and storage procedure is essential for ensuring data reliability.

Introduction/Definition: In surface mining, particularly open-pit operations, benches are horizontal steps or layers created as the pit is deepened. They provide safe access to different pit levels, allow for controlled excavation, and help maintain slope stability. Each bench acts as both a working platform and a safety barrier. Benches are designed considering factors such as rock type, equipment size, and safety regulations. The height and width of each bench are critical in optimizing production efficiency while ensuring worker and equipment safety. The image below illustrates a typical open-pit mining bench layout. As the mine expands downward, successive benches are formed, creating a stair-like profile. The main features include: • Bench Face: The exposed vertical surface where drilling and blasting take place. • Bench Height: The vertical distance between successive working levels, determined by equipment reach and geotechnical conditions. • Bench Width: The horizontal distance from the bench crest to the bench toe, providing space for haul roads, equipment maneuvering, and safety berms. • Haul Roads: Inclined pathways connecting benches, enabling trucks to transport ore and waste material efficiently. • Catch Berms: Safety ledges between benches to catch falling rocks and protect workers and equipment on lower levels. GEOLOGICAL & OPERATIONAL SIGNIFICANCE: Benches are fundamental to open-pit mine planning and safety. Proper bench design ensures stability, reduces the risk of slope failure, and allows efficient ore extraction. In addition, benches help in selective mining separating ore from waste with precision. Whether in gold, copper, or iron ore mining, well-engineered benches are the backbone of safe and productive surface mining operations.
